vernacular " !Raccoon-like Dog." It inhabits China and Japan.
As to structure, there is hardly anything that justifies its ex-
clusion from the genus Oanis. Garrod, however, mentions the
unusually large size of the Spigelian lobe of the liver.
Wortman and Malkens2 have instituted a genus JSTotJiocyon for
Dr. Mivart's species C. urostictus* and O. yarwidens, which are
both South American forms.
The genus Otocyon contains but one species, O. megalotis, an
African species, ranging pretty widely in that continent (from
the Cape to Somaliland, in sandy districts), and sometimes con-
fused with the Fennec on account of its long ears. Its prin-
cipal structural difference from other Dogs is that there is an
additional molar in each jaw, the molar formula being thus M ^
or even -J. Moreover the carnassial teeth are not so pro-
nounced, and Professor Huxley laid especial stress upon the
